A question on bisexuality and aging that just occured to me.

While on another forum an issue came to my mind that I was hoping someone might have some relevant data on, as currently I have 3 mainly unconfirmed sources regarding it.

If a person is bisexual in their early adulthood, it it common for that person to drift further towards desiring the same gender later in life?

I know of 3 cases where women who were purportedly bisexual early in life became more and more attracted to women in their later lives, at least one apparently becoming completely lesbian eventually.

While 3 possibly somewhat anecdotal sources of partial data are hardly enough to draw any conclusions from they were enough to pique my curiosity and to ask if there was any other data on the issue of bisexuals becoming more attracted to one gender as they aged.

I posted this here on the theory that it's at least a partially scientific question since I assume most people here accept orientation as a matter of neurological origin. I was hoping someone here might know if my question had been answered in some scientific study I was unaware of.

From what I've read female sexuality in particular tends to be a bit more fluid than men's. And bisexuality isn't 50/50. The percentages vary from people to people and, as you said, it's common for them to change throughout life.

There are also people who are technically bisexual, but identify as either straight or gay for various reasons. Biphobia is real and, weirdly, they get shit from both sides. Some doubt bisexuality even exists. Some think it's just a phase or that people can't make up their minds. When they are in an opposite-sex relationship they are seen as straight. When they are in same-sex relationship, they're gay. So for someone on the extreme end of the spectrum it can make sense to just say that the are straight or gay.

Which is somewhat true for me I suppose. I'm like 95+% straight and can't see myself in an actual relationship with a guy, so I might as well say I'm straight.

My best friend is bisexual and hasn't changed though she's now 60. She told me that her experience had been that she had to play straight among her straight friends, and lesbian among her lesbian friends as both seemed to reject bis.
